When rotating an object in the decorating mode you can object wobble when toggling rotation. This wobble can throw off the orentation and make it almost impossible for it to be lined up again without deleting the object and starting again.
This wobble can also allow the object to move away from the cursor, allowing it to be orbited around.
I've managed to get a video of it too
